Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If standard electrolysis is used on salt water, then hydrogen gas can be produced, but chlorine is generated as a hazardous by-product and electrode decomposition occurs

Engineering Contradiction:

Improvehydrogen productionVSAvoidchlorine generation and electrode decomposition

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the magnetic properties parameter of the electrode materials by selecting specific paramagnetic materials (Fe, Ni, Co) for cathodes and diamagnetic materials (Zn isotopes) for anodes. This material parameter change fundamentally alters the electrochemical reactions occurring at the electrodes, enabling hydrogen production from salt water without chlorine generation and electrode decomposition

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent employs composite electrode structures combining specific paramagnetic and diamagnetic materials. The use of zinc isotopes (64Zn, 66Zn, 67Zn, 68Zn, or 70Zn) as diamagnetic anode material combined with paramagnetic cathode materials creates a synergistic effect that prevents both chlorine generation and electrode decomposition while maintaining high hydrogen production efficiency

Inventive Principle:
